CSD

Pin to set the operation time of the lock protection circuit. Connect the capacitor between this pin and GND.

21

FAIL

Open collector output, with the output being “L” in following cases :

Abnormal Hall input, activation of the low-voltage protection circuit, activation of the lock protection circuit, and activation of the

overheat protection circuit.

23

CP2

Charge pump capacitor output pin. A capacitor is connected between CP1 and CP2.

24

CP1

25

LVS

Low-voltage protective voltage detection pin. A Zener diode is connected in series to set the detection voltage when the supply

voltage of 5V or more is to be detected.

26

V5

5V power pin (control circuit power supply). A capacitor is connected between this pin and GND.

27

V12

12V power pin (UL, VL, and WL output power supply). A capacitor is connected between this pin and GND.

28

VCC

Power pin. A capacitor is connected for stabilization between this pin and GND.

29

VB

Charge pump output pins (UH, VH, and WH output power supply). A capacitor is connected between this pin and VCC.

30

GND

GND pin.

31

RFGND GND sensing pin, which is connected to the GND side of low-resistance RF connected to the RF pin.

32

RF

Output current detection pin. Low-resistance RF is connected between RF and GND.

The output current is limited to the value set with IOUT = 0.1/RF. (Current limiting circuit)

-

FRAME This pin is connected internally with the metal in the bottom of IC.

Use both of them in the electrically open state.

13

NC

These can be used as wiring because they are not connected with the internal parts.
